Detects All Faces Automatically
BlazeFace AI finds every face in your photo — front-facing, angled, or partial. No manual cropping or tedious clicking on each person.
100% Private — Runs On-Device
Every pixel is processed in your browser via Google's MediaPipe. Your photos never leave your device — perfect for GDPR, sensitive media, and journalism.
Three Redaction Styles
Pick blur for a natural look, pixelate for classic anonymization, or black bar for maximum redaction — all with adjustable intensity.

How It Works
Drop or select your photo. We support JPG, PNG, and WebP up to 6000×6000 pixels.
Pick a redaction style — Blur, Pixelate, or Black Bar — and dial in intensity. The face detector downloads once (~3 MB) and caches for future use.

Frequently Asked Questions
Answers to the most common questions about AI face blurring and redaction.
Does this tool upload my photos to a server?
No. All processing happens entirely in your browser via Google's MediaPipe. Your photos never leave your device — upload, face detection, and download are 100% local and private. Perfect for GDPR, journalism, and any sensitive imagery.
What's the difference between Blur, Pixelate, and Black Bar?
Blur applies a soft Gaussian blur — the face shape stays visible but features are unreadable. Pixelate replaces the region with a mosaic grid — the most aggressive style, fully unrecognizable. Black Bar overlays a solid rectangle — used in journalism for maximum, unambiguous redaction.
How accurate is the face detection?
We use Google's BlazeFace short-range model — the same one running in MediaPipe. It detects front-facing and angled faces reliably down to ~30 pixels. Profile views and heavily occluded faces may be missed; for those cases, switch to a manual editor. We err on the side of catching more rather than fewer faces.
Can it handle multiple faces in one photo?
Yes. The detector runs in a single pass and finds every face it can see — group photos, classroom shots, and crowds all work. The intensity slider scales per face based on its size, so a small background face gets the same level of anonymization as a foreground face.
What image formats and sizes are supported?
JPG, JPEG, PNG, and WebP up to 6000×6000 pixels. Output is exported as PNG to preserve quality. Detection runs natively at full resolution — no down-sampling, no quality loss outside the redacted regions.
Is the AI Face Blur really free?
Yes. There is no signup, no credit card, no watermark, and no monthly limit. The tool runs entirely in your browser using the open-source MediaPipe BlazeFace model — we pay no inference costs, so you pay nothing.
